From c8075caf19b000b975349f8976958cedf7d2613a Mon Sep 17 00:00:00 2001 From: Gonglei Date: Tue, 30 Sep 2014 14:10:38 +0800 Subject: virtio: add a wrapper for virtio-backend initialization For better code sharing, add a helper function that handles reference counting of the virtio backend for virtio proxy devices.
